Background: Rectal varices are an infrequent but potentially serious cause of hematochezia. In this paper, the hemodynamics of rectal varices using endoscopic color Doppler ultrasonography (ECDUS) are evaluated. Method: This study consisted of six rectal variceal patients who had F2 type of the rectum, and four of the six had a positive red color sign. We monitored the color flow images of rectal varices. Results: Color flow images of rectal varices were obtained in all six patients. Color flow images of inflow and outflow vessels of rectal varices were obtained in all six patients. We performed endoscopic injection sclerotherapy (EIS) on three of the six patients. After EIS, ECDUS revealed the disappearance of the variceal blood flow in one case, and the decrease of blood flow in two cases. Conclusion: The technique of ECDUS is a useful modality for detecting rectal varices on color flow images and for evaluating the therapeutic effects of EIS.
